2D to 3D in FreeCAD: A Comprehensive Guide

FreeCAD is a popular open-source computer-aided design (CAD) software that offers a wide range of tools and features for creating 2D and 3D models. One of the most powerful capabilities of FreeCAD is its ability to convert 2D designs into 3D models. In this article, we will explore the process of converting 2D designs to 3D models in FreeCAD and provide a step-by-step guide on how to do it.

Why Convert 2D to 3D?

There are several reasons why you might want to convert a 2D design to a 3D model:

  • Enhanced visualization: 3D models provide a more realistic and detailed representation of your design, making it easier to visualize and communicate your ideas.
  • Improved design accuracy: 3D models can help you identify potential design flaws and improve the overall accuracy of your design.
  • Faster prototyping: With a 3D model, you can quickly create prototypes and test your design before moving to production.

Preparing Your 2D Design

Before you can convert your 2D design to a 3D model, you need to prepare your design in FreeCAD. Here are the steps to follow:

Step 1: Create a New Document

Open FreeCAD and create a new document by selecting File > New from the menu.

Step 2: Draw Your 2D Design

Use the Draft Workbench to draw your 2D design. You can use various tools such as lines, arcs, circles, and rectangles to create your design.

Step 3: Save Your 2D Design

Save your 2D design as a FreeCAD file (.FCStd) by selecting File > Save As from the menu.

Converting 2D to 3D

Now that your 2D design is prepared, it's time to convert it to a 3D model. Here are the steps to follow:

Step 1: Switch to the Part Workbench

Switch to the Part Workbench by selecting Part from the workbench toolbar or by pressing Ctrl + 2.

Step 2: Select Your 2D Design

Select your 2D design by clicking on it in the 3D view or by selecting it from the Tree View.

Step 3: Use the Extrude Tool

Use the Extrude Tool to convert your 2D design to a 3D model. You can access the Extrude Tool by selecting Part > Extrude from the menu or by clicking on the Extrude button in the toolbar.

Step 4: Set the Extrusion Parameters

Set the extrusion parameters by specifying the height and direction of the extrusion. You can also choose to extrude your design along a specific axis.

Step 5: Click OK to Extrude

Click OK to extrude your 2D design into a 3D model.

Tips and Tricks

Here are some tips and tricks to keep in mind when converting 2D to 3D in FreeCAD:

  • **Use the Draft Workbench to create your 2D design, as it provides more flexibility and control over your design.
  • **Use the Extrude Tool to convert your 2D design to a 3D model, as it provides more control over the extrusion process.
  • **Experiment with different extrusion parameters to achieve the desired result.
  • **Use the Undo and Redo features frequently to experiment with different design options.


Converting 2D designs to 3D models in FreeCAD is a powerful way to enhance your design capabilities. By following the steps outlined in this article, you can easily convert your 2D designs to 3D models and take your design skills to the next level. Remember to experiment with different tools and features in FreeCAD to unlock its full potential. Happy designing!
